ubuntu16.04虚拟win7——经验笔记——问题：Kernel driver not installed (rc=1908) error.

ubuntu16.04虚拟win7——经验笔记——问题：Kernel driver not installed (rc=1908) error. The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. executing  '/sbin/vboxconfig'  as root.

解决过程

1.刚刚在ubuntu software更新了系统，一重启，要打开虚拟机的时候出现如下

2.如何解决

于是照着报错的提示解决：

sudo /sbin/vboxconfig

出现：

[sudo] password for wangshuai: 
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.

There were problems setting up VirtualBox.  To re-start the set-up process, run
  /sbin/vboxconfig
as root.                                              

于是

wangshuai@wangshuai-Vostro:~$ head /var/log/vbox-install.log

echo >&2 ;							\
/bin/false)
mkdir -p /tmp/vbox.0/.tmp_versions ; rm -f /tmp/vbox.0/.tmp_versions/*
...
...
...略 

于是

wangshuai@wangshuai-Vostro:~$ uname -a

看来也没啥用

于是疯狂google

发现一个网址https://forums.virtualbox.org/viewtopic.php?t=82633，还是vbox官网的FAQ比较有用。

后面的回复的意思是说linux的kernel更新了的话一些application也得更新下，uname -a 发现我的linux内核是linux-headers-4.15.0-24-generic/，我的virtualbox版本是5.1.26

wangshuai@wangshuai-Vostro:/usr/src$ sudo apt-get install virtualbox-5.1

virtualbox-5.1 is already the newest version (5.1.26-117224~Ubuntu~xenial).
The following packages were automatically installed and are no longer required:
  libllvm4.0 linux-headers-4.13.0-43 linux-headers-4.13.0-43-generic linux-image-4.13.0-43-generic linux-image-extra-4.13.0-43-generic

Use 'sudo apt autoremove' to remove them.

根据另一个网址https://www.virtualbox.org/wiki/Changelog-5.1，得到上图及下面一些图，这图说5.1.24的vbox与内核为4.12或4.13兼容(不确定)，而且

貌似内核4.15支持vbox5.1.34，所以我决定把vbox升级一下试试，利用synaptic package manager把vbox5.1.26移除然后装上vbox5.1.34及相关的guest addition和 package。装完之后启动vbox就成功打开vbox了。
